vara-eth-tests

Write or update Vara-Eth integration tests for a new contract or API surface in this repository. Use when the task is to add a Vitest suite under test/ for another contract, following the successful VFT pattern with shared setup from test/common.ts and test/config.ts, Sails IDL parsing, router deployment, executable balance top-up, handle queries, injected transactions, or lower-level vara-eth-api coverage for mirror, router, query, signer, and promise flows.

Run a fully local Vara.eth development environment with ethexe, switch this repository to local RPC endpoints, fetch the local router address, and prepare `.env` for local integration-test debugging. Use when the task is to reproduce test failures locally, debug contract/program flows without testnet noise, or temporarily point the repo at a local ethexe dev node.
